I don’t think it really changes the narrative. 2020 was also a congressional election year, even had Trump won (as he appeared to want desperately) he could not have been assured of a Republican congress.
My argument is simple: Occam’s Razor
The Republicans in congress put the provision in solely as a gimmick to get past the CBO.
Frankly I don’t think legislators in either party are competent enough to have foreseen the consequences and even if they had been they wouldn’t have put a bomb like this in that would be more likely than not to backfire and affect them.
I just think that too often people interpret incompetence as malice, especially nowadays when things are so polarized that it’s fashionable to hate people who differ with one’s political opinions.
